. WASHER-HOLDER RIVZET-SETr lowing is a specification.

. -My invention relates toanimproveinent in rivet sets. my object being toadapt the rivet set to hold and deliver Washers to the rivets so that it will be unnecessary for the operator to lay down either his hammer '01" rivet set to mount the Washer onithe rivet. According to the. presentpractice a very large portion of the labor cost in certain riveting operations such as the rivetingof metal a roofs and light sheet metal articles, arises from the delay incident'to the nn'mberof nnnecessary movement's required o'f the operator in connection with each riveting oper- :ation. The riveting tool is held in the left hand, the 'hammerjin the right, and the washers must be carried in the pocket or in some suita'ble container. After each "rivet has been forced thronghthe metal layers,

one or the other of the tools in handmust'be laid aside; atfwasher picked njpfand placed over "the exposed end of the rivet, and the tool that was laid aside mi' st be taken in hand aga" -befo'rethe riveting operationfc'an be performed.

The object of my invention isto'enable the washers to be applied'tothe rivets without the delayincident to these varied movements -on the part or the operator, "the rivet set being adapted to contain the washers and to ex-pose themiin such manner that they presence :in the rivet set can be easily mounted upontherivet without appreciable loss of time. p

A further object of myinvention is to so design the washer retaining means that their I I will not interfere with its normal use.

Further objects- 'of iny -"i-nvention are to simplify the means for controlling by "a thumb operated slide the, release; of washers the means for maintaining 'a' ten si-"on on the washers to feed themja'nd hold them firmly in'the tool against rattling; andi'n various other novel details of construction and; arrangementsiof parts which are hereinafter claimed, and Whieh in their preferred embodinient are illustrated in "the a company.

ing drawings forming cation and 1n which Figure 1 'is'a side elevation of a rivet set a partof this specifiwith the guard cap in locked position to prevent {the removal of washers. Fig. 2 is a side elevation of Fig.1. Fig. 3 is a view similar to Fig. 2 showing the cover opened Wide andexposing the internal mechanism for mountingand feeding the Washers. Fig. llis abottom view of Fig. 1. Fig. 5 is a transverse cross sectional view on the line w s of Fig. 1. Fig. 6 is an enlarged detail view showing the rivet'set in position for delivering a washer to a rivet. detail view of the slotted plate holder for the washer'rod. I M

Similar reference numerals refer to similar parts throughout "the drawings.

lnfthe preferred embodiment of my inven- -"ti-on illnstrated, the rivet set is made slightly longer 'andwider than the present standard type of steel rivet set andit is provided with a longitudinal washer pocket 2 in a Wider side face' tl-iereof, Which ipocket extends from a point adjacent to its bottom end Well up into the body of the tool, and is made slightly wider than the diameter of the Fig. .7 is a washers with a bottom cylindrical in cross section. p

The lowerend Wall of the pocket has a slot 3 which opens 'therethrongh into a countersn-nk recess 4 in the bottom end of the rivet set. The openside of the pocket is normally closed by 'a swinging "cover plate 5 which is so shaped that when in operating position it lies flat iipon the side face of the'rivet set and' coversall but the extreme bottom end ofthe pocket '2. It is pivotally mounted on 'the'to'ol and'at its other side edge the cover has a notch '7 at an intermediate point adaptedto swin nnder the head of; a stop pin 8 on by a pin6 near one side edge thereof '1 the opposite side of the pocket on the'same side. The lower end of the cover is also adapted to icatchnnder the'head of a second headed *s'top pin 9 near the lower corner of the rivet set. When the "cover has been swung on its pivot to engage the two stop pins 8 and 9, its lower edge, as seen inFig.

1 will lie diagonally of the lower end of the pocket Q-and approach the bottomend wall 1 0. thereof so closely as to preventthepassageor a washer nnder it. 1 i

"The cover is provided with a longitudiup at 13 to furnish a finger hold for swing-- ing it about its pivot pin 6.

In the upper end'of the" pocket I provide a pair of opposite side notches 14 which 1'6;

' .ceive a transverse slotted plate rod 15 and detachably hold it in position across the upper end of the pocket. Y A rod 16 for-the washers projects with a loosefit through the slot-24: in this plate15 and is provided with a head17 to prevent its becoming disengaged therefrom while the plate remains seated inthe pocket. I mount on'this rod 16 a slide plate 18 having a collar 19 to prevent itcockingwhen it is grasped by its handle portion-20 and adjusted longitudinally of the pin to increase the tension upon a coiled spring 21 that surrounds the rod 16 and is'interposed between the plate 18 and a presser plate 22 which is adapted to force a series of washers 23 strung upon the lower end of therod 16 against the end wall 10. 1

The slot 24 permits the rod 16 to be swung up out of the pocket-so that the washers can be conveniently mounted thereon until the presser, plate 22 isforced up and the spring 21 is put under considerable tension. In this position, when the rod 16 is returned to the recess 2 the spring will hold the washers pressed against the bottom wall 10 of the recess whilev the rod: 16 clears the lower washer and holds its opening in line with the inner. end of 3 the slot 8. This lower washer however is of the recess by the bottom edge of the cover I plate 5 when in the position shown in Fig. 1.

The bottom edge of the V l V coverabove the slot 3 is provided with a notch 25 so that its side edges only serve as the rivet retaining means. If the upper end of the cover plate however is swung slightly to the left, its lower end clears the lower washer and thereupon the tool is placed .over the exposed end 25 of a rivet 26, upon which it is desired to mount a wa sher,.so that the rivet will pass up through the opening 3 and into the central opening set so that the rivet will draw the washer out from the pocket by passingit under the cover 5, thewasher will be left-mountedon above the top of the washer. The rivet set is provided with the customary riveting socket 27 and punch hole 28 so that the rivet notches 12 in one side edge of the the purposes hereinafter described:

held against the removal I of the bottom washer. By shifting the rivet Y pressed up at 30 so that it will" clearthe handle; The cover on the other side of the from the notch 29so that it will project up through the slot in the cover plate. makes it convenient to grasp the handle and advance the rear-slide plate along the slot slot will strike the handle and raise it up This Y to engage the handle in one or the other of thenotches 12 to take up the slack in the spring21 as washers are fed from the pocket. The countersunk recess, 4: in the bottom of the rivet set protects the thin walls 10 from liability to fracturein the ordinary use of the tool. 4
